CARLINE CONSTRUCTION.

' Application filed June 1,

To all whom it may concern:

Be it known that I, JOHN W. BERNBAUM, a citizen of the United States, residing 1n Chicago in the county of Cook and State of Illinois, have invented a new and useful Improvement in Carline Constructions, of which the following is a specification.

This invent-ion relates to carline constructions; such as are more particularly designed for use in freight car roof frames; the invention has for an object the provision of a simply constructed well-balanced carline that is not only strongly braced in its middle portion, but also is especially reinforced at the points of attachment to the side frame inembersor side plates, with the result that the carline, as a whole, is stiffened and made especially resistant at the points where vertical, horizontal and torsional stresses are most likely to occur.

In addition to the general object recited above, the invention includes among its objects such other improvements and advantages in construction and operation as are found to obtain in the structures and devices hereinafter described or claimed.

In the accompanying drawings, forming a part of this specification, and showing, for purposes of exemplification, a preferred form and manner in which the invention may be embodied and practiced, but without limiting the claimed invention specifically to such illustrative instance or instances:

Figure 1 is a plan view of a portion of a car roof frame provided With a carline constructed in accordance with the present improvements v Fig. 2 is a transverse section through the car roof, showing the carline in longitudinal elevation;

Fig. 3 is an enlarged fragmentary view of the end portion of the carline adjacent to the side plate and showing the mode of attachment thereto; j

Fig. 4 is an enlarged vertical section on the line 4-4 of Fig. 2;

Fig. 5 is a perspective of the end of the carline and of the top reinforcing plate.

Fig. 6 is a plan view of a portion of one side of a car roof frame, illustrating a modification;

Fig. 7 is a transverse section through the car roof illustrated in Fig. 6, showing the carline in longitudinal elevation;

1920. sem No. 385,459.

Fig. 8 is an enlarged vertical section on the line 8-8 of Fig. 7 and Fig. 9 is an enlarged vertical section on the line 9l-9 of Fig. 7 c

The same characters of the-same parts throughout the several views of the drawings. 1 In both forms of the invention shown, the

carline 21 consists of a single steel bar, of I channel or U-shape in cross section,- comprismg the web 22 of U or "channel cross section and lateral fianges23, bent oppositely reference indicate from the top edges of the opposite side members of the web. As shown, the web 22 is downwardly inclined or tapered from the middle portion of the carline to the opposite ends-thereof, at the angle adapted to impart the desired pitch to the roof; and,

preferably, said web gradually diminishes in' depth from'its "middle portion or horizontal portion2 l of the latera-l'fla-nges 28, to the opposite ends of the carline. The

site ends, the increasein metal in the lateral flanges towards the ends being proportionate to the decrease in metal in the web.

At the opposite ends of the web 22 and lateral flanges 23, the carline is formed with downturned vertical flanges 25. The opposite ends of the carline are secured to the side frame members, such as the side plates 26 of the car roof frame, and in order to strengthen the parts at the points of attachment of the carline to said side plates, there are provided; top or reinforcing plates 27 in the form-of angle plates having lateral webs 28 adapted to overlie and be secured by bolts 29 to the end portions of the lateral flanges 23 and vertical webs 30 adapted to rest against the outer faces. of the downturned flanges 25 at the opposite ends of the carline, As shown in Figs. 2 and 3, the

vertical webs 30 of the top plates are interposed between the down-turned flanges 25 and the inner faces of the side plates 26,

and the opposite ends of the carline are secured to said side plates by bolts 81 respectively located on opposite sides of the channel or web 22 and passed through the down-turned flanges 25, the vertical webs 30 of the top plates, and the side plates 26.

In the form of the invention illustrated in Figs. 6 to 9 inclusive, the side plates 26 :are reinforced by angle bars 32 extending along with the side plates and having horizontal webs 38 beneath the bottom faces of the side plates and vertical webs 3a interposed between the vertical webs 80 of the top plates 27 and the inner faces of the side plates. The bolts 31 for securing the carline to the side plates are passed through the vertical webs 34 of the reinforcing angle bars 32, as well as the down-turned flanges Q5 ofuthe carline, the vertical webs 30 of the top plates, and the side plates 26.

The carline illustrated in the drawings may support in the usual way the ridge pole 35,;and the purlins 36, these being bolted to the lateral flanges 23 of the carline.

The invention as hereinabove set forth is embodied in a particular form of con struction but may be variously embodied within the scope of the claims hereinafter made.

I claim:

1. In a carline construction, the combination with the side plates of a. car roof frame;

of a carline embodying a single steel bar at the opposite ends of the carline; reinforcing plates of angle-formation positioned with their lateral webs secured to the lateral flanges of the carline and with their vertical webs resting against the outer faces of the aforesaid down-turned flanges; and bolts passed through the down-turned flanges, the vertical webs of the reinforcing members and the side plates, for securing the carline to the side plates; substantially as specified.

2. In a carline construction, the combination with the side plates of a car roof frame; of a carline embodying a single steel bar :lormed with a depending web of channel section, with lateral flanges bent outwardly from the top of the side members of said web, and with down-turned flanges at the opposite ends of the carline; reinforcing members having portions overlying the end portions of the lateral flanges and engaging the outer faces of the down-turned flanges; and means for securing the down-turned flanges and the reinforcing members to the side plates; substantially as specified.

in a carline construction, the combination with the side plates of a car roof frame; of angle bars positioned with their vertical and horizontal webs respectively engaging the inner side and bottom faces of the side plates; carline embodying a single steel bar med with a web of channel section, with lateral flanges bent outwardly from the side members of said web, and with down-turned flanges at the opposite ends of the carline; top plates having portions overlying the end portions of the lateral flanges and engaging the outer faces of the down-turned flanges; and means for securing the down-tinned flanges, and the top plates to the reinforcing bars and the side plates; substantially as specified.

JOHN W. BERNBAUM.
